How do I add 1 month to today? I don't want to add 30 days or anything, I just want to get to the next month and I have to be able to cross years. so if today is 2/1/2015 I want to find March is next; if today is 12/31/2015 I want to find Jan is next. Do I need a lookup or is there a date function that would get me this?
